The very Duple Dominant’s I learned to drive on in 1984. Grey Green now of course gone, but looking on street view, I think the office building (Grey Green)still exists. Please correct me if i’m wrong.

Also in the episode “Slow Bus To Chingford” the actual bus depot they used was my old bus garage. It was the Grey Green Coach deopot in Stamford Hill North London (N16). sadly it has now been demolished and made way for a new housing estate.
